As seasons change, so does the weather and its effect on ash ponds. In the wintertime, ash ponds can freeze dry, resulting in fugitive dust particles PM10 and PM2.5 of coal ash lifting from the surface. In the summertime, evaporation and drainage of ash ponds can create dust problems as the ash begins to dry. Sealing and stabilizing ash ponds is the only way to prevent ash from becoming airborne and creating dust, threatening the safety and health of people working and living near dust-prone areas.
